Answer 1

Create two-dimensional array Initializing elements in the array:

PHP:

$arr = array
(
array(22,18),
array(15,13),
array(5,2),
array(17,15)
);

C#:

int[,] arr = new int[5, 2] {{0,0}, {1,2}, {2,4}, {3,6}, {4,8} };

python:

from array import * arr = [[11, 12, 5, 2], [15, 6,10], [10, 8, 12, 5], [12,15,8,6]] 

Access element in array:

PHP:

To get access to the elements of the $arr array we must point to the two indices (row and column):

$arr[0, 0] value is 22

$arr[2,1] value is 2

$arr[3, 0] value is 17

C#:

To get access to the elements of the arr array we must point to the two indices (row and column):

arr[0, 0] value is 0

arr[2, 1] value is 4

arr[3,0] value is 3

python:

To get access to the elements of the arr array we must point to the two indices (row and column):

arr[2][1] value is 8

arr[1][1] value is 6

arr[3][3] vlaue is 6
